The gradient is smooth, and RGB colors quite acurate, it looks nice,
unfortunately the full palette tends toward the pastels. The same issue as with
the freecolour-HLC CIELAB reference palette.
Need more highly saturated RGB colors. For example the "tonal" technical
palette--perhaps alligh the name/color pairings (from the tonal 58% row) across
these two RGB centric palettes adjusting the starting point. But if just an
extension--your call on that stylistic facet.
Also, to simplify things for translators should this be added to core, I would
suggest you adopt the color naming from the tonal palette of Spring Green and
Chartreuse rather than the non-standard Lime and Turquoise you've assigned.

6.1 is string and feature frozen, we are committed to a RYB palette. But
improving the RGB/HSI color correctness for RYB hue, tints and especially the
shades would be a valid patch for the release. Looking forward to see if you
can improve on the Gosett & Chen algorithm used by Eddy.

IIRC several unit tests pick up the defined COL_DEFAULT_SHAPE_FILLING and
COL_DEFAULT_SHAPE_STROKE [1] and automated qa unit tests break when we've
removed those specific values from the standard.soc, or have changed their
assigned values in the xdef.hxx... Heiko?
